ITPEC IP October 2019 Question 46
ITPEC IP October 2019 — Question 46 of 100
Modifying software after a defect is reported in a production system is software maintenance. Maintenance begins after delivery and operation and includes correcting defects, adapting to environmental changes, improving qualities, and preventing future problems.
Answer (d)
Why not others:
- tuning during system testing is part of development and verification before release
- fixing a fault found during acceptance testing occurs before acceptance
- adding a missing function during unit testing is still development work
Key rule: Changes to operational, delivered software are maintenance; corrections made during pre-release testing remain development activities.
